Aerobic oxygen MBR sewage treatment experimental device

Through experiment hopes to achieve the following purpose:

1. Understand the basic operation process of the treatment of multi -functional sewage treatment of unnoram -inferior, good oxygen, and "MBR" membrane.

2. Deepen the understanding and basic principles of this process.

3. Master the technical parameters and practical knowledge of this process.

4. The A/O method -based processing process is adopted in front of this device. The subsequent film filtering method can be used.

The sewage is removed into the water tank after removing large particles and fibrous impurities. Then enter the anaerobic tank through the pump metering tank for acidification and hydrolysis. At this stage, the average quality of the sewage is regulated, and the characteristics of the large -molecular structure that is not easy to degrade with the characteristics of short -generation, poor activity, and prone to breeding and growth are used to hydrolyze them into small molecules and soluble compounds. Nitrification, eventually nitrogen pollution. The aeration of the sewage flowing into the puzzle with fillers is exposed to the oxidation pool.
